  • ffmpeg export multichannel audio -map

    8 avril 2014, par speedyrazor

    I am trying to export all audio channels from a multichannel quicktime file with ffmpeg which has the following audio configuration, but am unsure if the command below is correct. All the files look and play correct in Quicktime player except the L+R_Total.wav which refuses to play in Quicktime player but plays fine in VLC, so not sure if i'm using the wrong command :

    Track 1 - mono
    
Track 2 - mono
    
Track 3 - mono
    
Track 4 - mono
    
Track 5 - mono
    
Track 6 - mono
    
Track 7 - stereo

    I am using :

    /Users/me/Desktop/python/ffmpeg/ffmpeg -i /Users/me/Desktop/test.mov -acodec pcm_s24le -map 0:1 -y Left.wav -acodec pcm_s24le -map 0:2 Right.wav -acodec pcm_s24le -map 0:3 Center.wav -acodec pcm_s24le -map 0:4 LFE.wav -acodec pcm_s24le -map 0:5 Left_Surround.wav -acodec pcm_s24le -map 0:6 Right_Surround.wav -acodec pcm_s24le -map 0:7 Left+Right_Total.wav

    Here is the printout from the terminal :

  • Does ffmpeg version 0.7 support -codec copy option ? [migrated]

    2 avril 2014, par Boris Šuška

    I have to use ffmpeg version 0.7.15 to merge video (without audio) and audio file into one video file with audio. I would like to use command ffmpeg without re-encoding.

    I used this with newer version of ffmpeg command

    ffmpeg -y -i "video.mp4" -i "audio.mp4" -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0 "output.mp4"

    I need similar command for version 0.7.15, this is not working :

    ffmpeg -y -i "video.mp4" -i "audio.mp4" -vcodec copy -acodec copy -strict experimental -map 0:v:0 -map 1:a:0 "output.mp4"

    but this command works :

    ffmpeg -y -i "video.mp4" -i "audio.mp4" -vcodec libx264 -acodec aac -strict experimental -map 0:v:0 -map 1:a:0 "output.mp4"

    Does ffmpeg version 0.7.x support -vcodec copy and -acodec copy or something similar ? If no which first version supports this ?

    Update :
    -vcodec copy -acodec copy is not working for version 0.7.15 means if I have two files :

    -rwxrwxrwx 1 vagrant vagrant  2066268 Apr  1 11:41 audio.mp4
    
-rwxrwxrwx 1 vagrant vagrant 33172453 Apr  1 11:41 video.mp4

    and I run ffmpeg command with -vcodec copy and -acodec copy options I get this output :
